Sonic 2 CD Version never got released, and it's still up in the air if it ever existed, all info about it comes from magazine previews before Sonic CD was announced so it's possible it was that in beta form.

I would have changed quite a few in that list, but I totally would have said Sonic 3 & Knuckles at top spot rather than just Sonic 3, cause technically they were spose to be one big game.

all the sonic games feel like mario spinoffs gone wrong. the 3d games suck and you move so fast in the 2d ones that you can barely enjoy the game. Just hold the analog stick in the right direction and spam the jump button. The only fun one to me was the shadow game and the 3d gamecube one.

I've always heard Sonic Colors is just that dang good but never had a chance to find out for myself. One of these days, I will.

Also, I think I've reached a point where I can't tell if my love for Sonic Adventure is all nostalgia or if it's actually as awesome as I remember. It sure didn't age well visually, but I thought the story was really fun.
